Do you need a mold inspector license in Pennsylvania?
Pennsylvania does not license or register mold inspectors. Pennsylvania is mostly cold humid-continental zone 5A (mixed-humid 4A around Philadelphia, colder 6A in the northern tier), so winter cold-surface and interstitial condensation plus basement dampness lead, with summer humidity a secondary load. The Pennsylvania Department of Health publishes mold guidance but issues no mold credential. Pennsylvania inspectors typically hold a voluntary IICRC or ACAC certification.
Is a license required?
Pennsylvania does not license mold inspectors or assessors at the state level. Inspectors typically hold a voluntary certification (such as IICRC or ACAC) rather than a state license.

Common questions
Do you need a license to be a mold inspector in Pennsylvania?
No. Pennsylvania issues no state mold-inspector license, so there is no state exam or registration to complete. Inspectors instead show competence through voluntary certification such as IICRC or ACAC and by following recognized industry standards.
Who regulates mold inspection in Pennsylvania?
No single board regulates mold inspection in Pennsylvania. The state's environmental and health agencies publish general mold guidance instead: https://www.health.pa.gov/.
